{      The RHFAM/VE event processor is responsible for maintaining the
{ current LCN status as viewed from the local mainframe.  The event processor
{ is a system task defined in a system prolog by the DEFINE_SYSTEM_TASK
{ command.  The system task is initiated by an ACTIVATE_SYSTEM_TASK command
{ and remains active until either a DEACTIVATE_SYSTEM_TASK command or
{ a deadstart occurs (a recovery deadstart will not automatically restart
{ the task).
{
{      The event processor has several major tasks that it performs:
{
{ 1)   The system task initializes the RHFAM/VE environment:
{
{      a)  The currently installed RHFAM/VE configuration file is
{          activated ($SYSTEM.RHFAM.CONFIGURATION.$HIGH)
{
{      b)  All system resources that are used by RHFAM/VE are reserved
{          (the NADs and the PPs).
{
{      c)  The microcode is loaded in the PPs (driver NPDR) and the
{          microcode is loaded in the NADs
{          ($SYSTEM.RHFAM.MICROCODE.C180.$HIGH).
{
{ 2)   Maintain the current status of all connection end points that are
{      defined in each of the defined local NADs.
{
{ 3)   When an incoming connect request is received the connect request
{      is queued for the corresponding server application and a
{      server job is initiated (if necessary).
{
{ 4)   If a task is suspended waiting for an RHFAM/VE event that has occurred,
{      the event that occurred is flagged and the task is restarted.
{
{ 5)   Monitor the start-up server jobs and the processing of incoming
{      connect requests to make sure that a response is given to
{      a remote host.
{
{ 6)   Maintain the availability information of the paths that are
{      accessable from this host.
{
{ 7)   Perform automatic dump and reload functions for malfunctioning NADs
{      that are maintained by this host.
{
{ 8)   Perform RHFAM/VE termination process:
{
{      a)  Terminate all incoming connections and currently active
{          connections.
{
{      b)  Wake up all tasks waiting for events.
{
{      c)  Idle down the PP drivers.
{
{      d)  Release all resources (NADs and PPs).
{
{      e)  Deactivate the RHFAM/VE configuration.
